A new software update for the Apple TV, tvOS 11.2, arrived today.
It adds the previously delayed sports section to the TV app and allows users to change the rules about how the Apple TV 4K deals with standard dynamic range (SDR) content on high dynamic range (HDR) TVs.

The update also offers users a solution to frame-pacing problems that occurred as a result of the gadget’s default behavior of forcing all content to play at 60Hz.
Arguably the most notable addition is a new setting that allows you to force the Apple TV to match its video output settings to the content you’re watching on a case-by-case basis.

This resulted in subpar SDR image quality with some content.
Similarly, the Apple TV 4K automatically output content at 60Hz to 60Hz TVs, even if the source content was, say, 24Hz, or 50Hz.
